Page 5: GWeld (Generalized Weld)

  • gweld panel
  • Figure 1 - GWeld Interface

Purpose: *CONSTRAINED_GENERALIZED_WELD has many variants in LS-DYNA, but this interface is specifically for showing, creating, modifying, and deleting *CONSTRAINED_GENERALIZED_WELD_SPOT cards. Failure parameters can be set as desired and used for the welds being created. Also these parameters can be modified as necessary for each weld.

Controls:

  • rbs Show - Show existing *CONSTRAINED_GENERALIZED_WELD_SPOT entities
  • rb Create - Create new *CONSTRAINED_GENERALIZED_WELD_SPOT entities
  • rb Modify - Modify existing *CONSTRAINED_GENERALIZED_WELD_SPOT entities
  • rb Delete - Delete existing *CONSTRAINED_GENERALIZED_WELD_SPOT entities

For Show, Modify, and Delete, the Entity Operation Interface is displayed in the secondary controls area. For Create, the General Selection Interface is displayed in the secondary controls area.
